Area forecast discussion, Mar 6, 1:07 PM EST, 3 hours 4 minutes before
Area Forecast Discussion
National Weather Service Boston/Norton MA
107 PM EST Fri Mar 6 2020
.SYNOPSIS...
High pressure over eastern New England early this morning will drift
offshore today. A powerful ocean storm develops off the Mid Atlantic
coast this evening, then tracks well south of New England
tonight into early Saturday. This storm will bring very strong
winds to Cape Cod and the Islands with accumulating snow for the
south coast of MA and RI, heaviest Cape Cod, Marthas Vineyard
and Nantucket before ending early Saturday. Fair and cool
weather Saturday night, then fair and much milder weather
follows for Sunday and Monday. Another weather system may bring
scattered showers and isolated thunderstorms on Tuesday. Cooler
air and scattered showers Wednesday and Thursday.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
1 PM update...
Clouds are overspreading SNE as precip shield slowly lifts
north from mid Atlc region and south of Long Island. Rest of
daylight hours should remain dry with just a low prob of some
spotty light rain near the south coast and portions of CT
toward evening.
Previous discussion...
Plenty of sunshine this morning across much of SNE but clouds
will increase and thicken this afternoon from the south and the
west. Deepening low emerging off the mid Atlc coast will begin
to increase winds over Cape/Islands through the afternoon but
much of the region will likely remain dry. Just a low risk for
spotty light rain late in the day from SW MA/CT to the south
coast and islands. With sunshine into early afternoon, highs
will reach well into the 40s, and around 50 for portions of CT
valley and interior SE MA.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SATURDAY/...
415 AM Update...
*** Strong to Damaging Winds Likely Cape Cod & Islands ***
*** Accumulating Snow Likely Cape Cod & Islands ***
*** Minor Coastal Flooding Likely Cape Cod & Islands ***
945 AM update...
No changes to current forecast/headlines at this time. 12z NAM
trended slightly east but main risk of accumulating snow
remains across Cape/Islands.
Winds ... high forecast confidence
Amplifying mid level northern stream trough phases with southern
stream energy off the Mid Atlantic coast tonight yielding
bombogenesis with low pressure deepening about 24 mbs in 12 hrs! The
low bottoms out around 963 to 967 mb (depending on model of choice)
at 09z Sat south of the 40N/70W benchmark. This results in very
strong to damaging northeast winds of 30 to 40 mph with gusts up to
65 mph likely across Cape Cod and Islands, strongest over Nantucket
where there is a low prob for an hour or two of hurricane force
gusts 64 kt/74 mph. As temps cool aloft low level lapse rates
steepen and model soundings at ACK and CHH indicate high probability
of 60+ mph gusts. Therefore will upgrade the High Wind Watch for
Cape Cod, Nantucket and Marthas Vineyard to a High Wind Warning.
Wind speeds of this magnitude expecting at least some tree damage
along with isolated to scattered power outages with greatest impact
across Nantucket. Wind advisories continue for coastal Plymouth to
coastal Bristol to Block Island. Model soundings also support gusts
greater than 45 mph for coastal Essex county/Cape Ann. Thus will
include this area in the Wind Advisory.
Accumulating Snow ... low to moderate forecast confidence.
00z Hi Res and Global guidance have all trended stronger with
offshore low with models indicating a 963-967 mb low tracking south
of the 40N/70W benchmark early Sat morning. Despite the large
distance from shore this intense cyclone has a very large wind field
with its warm/moist conveyor belt extending well to the northwest
and now wrapping cyclonically across southeast MA tonight into early
Saturday morning. Thus increasing the risk for accumulating snow.
Also wind field in the 700-500 layer supporting potential for
mesoscale snow bands via deformation. As a result models have
trended up with qpf and much of the guidance offering 0.25-0.50
across Cape Cod and the Islands with potentially greater than 0.50
inches for Nantucket. Snow to liquid ratios could be greater than 10
to 1 as some of the guidance shows max omega occurring the snow
growth region. However low level temperatures are marginal for
accumulating snow so unless heavier snow bands track northward over
Cape Cod and the Islands, snow may be difficult to accumulate on
paved surfaces. However if heavier qpf does materialize boundary
layer will cool and accumulating snow will commence. HREF hourly
snowfall rates support this idea with probs up to 50% for 1 inch
hourly snowfall rates. Given recent northwest trends along with
anomalous sub-970 mb low and best forcing for ascent potentially in
snow growth region along with banding signature, leaned toward this
heavier qpf scenario (although not to the extent of the Canadian
Rgem model). This translates to a coating to 2 inches of snow across
southern RI into south coastal MA including Plymouth county with 2-4
inches of snow for Cape Cod and Marthas Vineyard with 3-5 inches for
Nantucket. Therefore have issued a Winter Weather Advisory for this
region. However a shift of 50 miles in storm track will alter these
snowfall totals so this forecast is subject to change. Regardless of
exact snow totals there will be a 6-9 hour of winter weather with
strong NE winds yielding blowing snow and poor vsby. Could also be
some ocean effect enhancement early Sat morning as 925 mb temps
lower to about -10C, steepening low level lapse rates and increasing
moisture and heat fluxes for ocean effect snow showers.
Saturday ...
Morning snow over Cape Cod and Islands should exit by midday but
strong north winds will continue. Elsewhere dry weather but windy
and cool conditions. Highs in the upper 30s to lower 40s, a few degs
cooler than normal but will feel colder given gusty north winds.
&&
.LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/...
Highlights...
* Dry and quiet weather expected Saturday night through much of
Monday. Temperatures trending upward during this timeframe.
* Next system moves in sometime between Monday evening and
Wednesday. Drier weather potentially returns on Thursday.
Temperatures trend downward Tuesday through Thursday.
Details...
Saturday night through Monday...
A negatively tilted trough will be located offshore Saturday
evening, while a ridge axis is just east of the Mississippi River
Valley. The trough will continue lifting northeastward offshore. The
ridge will build eastward overnight. The surface high will build
into the Carolinas and nudge its influence into the Northeast. Winds
will gradually back from the north the to the west.
Flow aloft at 850 hPa switches from northerly cold air advection to
weak warm air advection by Sunday morning. Skies will be clear with
gusty winds continuing to diminish as the high relaxes the pressure
gradient. Expect this to be the coldest night of the long term with
lows generally in the 20s.
The ridge axis will continue to build eastward Sunday through
Monday. Expect southwesterly warm air advection through this time
period with 0 to +10 degree Celsius 850 hPa air moving in. Expect
the highest temperatures on Monday as the warmest air moves in.
Highs on Sunday will generally be in the 50s. On Monday readings
range from the mid 50s to the low 60s.
It still may be a bit breezy on Sunday and Monday as lapse rates
will be nearly adiabatic during the day. So, it shouldn't be hard to
tap into the 15-20 kts of wind aloft once the mixed layer grows.
Monday night through Thursday...
Confidence in the forecast lowers during this timeframe as models
spread out in the track, intensity and speed of the next system
moving in. A shortwave trough will lift from the Mid Mississippi
River Valley into the eastern Great Lakes. A surface low develops
and lifts into the region along with this wave. As of right now it
looks like this mainly brings precipitation in on Tuesday, but
doesn't appear to be a washout at this point in time. Used the NBM
guidance due to uncertainty.
Another trough digs in from the the Upper Midwest on Wednesday and
could bring more precipitation. Still enough spread amongst guidance
in mass fields that it is hard to pin point how things will
progress. A broad low may develop nearby or over the region bringing
precipitation chances.
Confidence still low on Thursday as a ridge axis may build in per
the GFS/ECMWF, but the GEM guidance keeps the region under cyclonic
flow. There are some significant differences in comparison to the
previous runs of these models, so have kept the NBM guidance this
far out.

.TIDES/COASTAL FLOODING...
415 AM update ...
Powerful low passes south of New England late tonight/early Sat with
surface pressure 963-967 mb! Fortunately tides are not
astronomically high and also strongest wind and storm occurs around
low tide (3 am - 4 am). This combined with pressure rises occurring
toward high tide Sat will limit coastal flooding to minor category.
Storm surge values at high tide will range between 1-2 ft, perhaps
slightly higher at Nantucket and Cape Cod. Given minor inundation
expected will post a Coastal Flood Advisory from Plymouth county
southward thru Cape Cod, Nantucket and Marthas Vineyard.
